SATHEE: Kinematics Question 212

Kinematics Question 212

Question: A body sliding on a smooth inclined plane requires 4 seconds to reach the bottom starting from rest at the top. How much time does it take to cover one-fourth distance starting from rest at the top [BHU 1998]

Options:

A) 1 s

B) 2 s

C) 4 s

D) 16 s

Show Answer

Answer:

Correct Answer: B

Solution:

$S = u t + \frac{1}{2} a t^{2} = 0 + \frac{1}{2} a t^{2}$ Hence $t \propto \sqrt{S}$ i.e., if S becomes one-fourth then t will become half i.e., 2 sec
